Hey!
does anybody know the answers to any of these questions?

1. how many balls can we grab up off the ground? also, what constitutes as "grabbing"?

2. how many balls can our bot hold during the match? also, what constitutes as "holding a ball"?

3. are there any penalties for holding too many balls?

4. can we put anything over our bot? i.e. a net or piece of sheet metal on the back to prevent teams from wedging balls onto our bot.
